When mixed in a 80:1 ratio of
fuel to additive the Outlaw averaged a RON reading of 101.2 and a MON
rating of 91.4. Giving Outlaw in a concentration of 80:1 an
AKI
of 96.3 when mixed with 93 pump fuel. Give the lean additive fuel
ratio, this is impressive for a 9 dollar bottle of commonly available
octane booster.
When used an a concentration of 40:1, over the recommended maximum,
102.2 RON was achieved with a MON of 92.1 giving it a AKI of 97.15.
As with other boosters tested, the effectiveness levels off after a
certain ratio. IE, just because 1oz gives 3 octane numbers
does not mean 2oz will give 6. More is not better here.
This is one of the few boosters able that can with just one bottle
raise the octane of an entire tank a significant amount. In a lightly
tuned engine this could be a good product to gain a few octane numbers
for track days. Two bottles in a full tank would provide a healthy
increase in octane. While race fuel would be better, for
occasional track days this would be a great fuel supplement.
